Islam is the state religion in Oman, introduced during Muhammad's lifetime in the early 7th century. Muhammad appointed Amr ibn al-As as governor, who remained until Muhammad's death in 632 CE. Amr and Sa'id ibn Aws al-Ansari delivered Muhammad's letter to the Al-Julanda brothers; the rulers of Oman, inviting them to embrace Islam. This peaceful mission marked the beginning of Islam in Oman. Today, 85.9% of Oman's population is Muslim, with slightly over 45% following Sunni Islam, and around 45% Ibadi Islam, with the other 5% identifying as Shia Muslims.[2][3]
